You need a table with the content of sodium per serving.
This is the table:
butter 1 pat 41mg
coffe 250 ml 0
eggs 1 serving 60mg
toast 1 slice 170mg
orange
juice 250 ml 4 mg
With that table you can calculate the content of sodium in the breakfast, this way:
orange juice: 1 41 mg = 4 mg
2 eggs: 260mg = 120 mg
2 slices of toast with butter on each: 2 ( 170mg+41mg) = 422mg
and coffee: 1 0 = 0
The total sodium ingested is: 4 mg + 120 mg + 422 mg = 546 mg
Answer: 546 mg
